Fig. 11 is a broken detailed view disclosing the means for locking the lower beating elements against operation while the sliding mattress support is being moved, or is out of operative position, and for preventing withdrawal of said support while the said lower beating element is in operation.

Fig. 12 is an enlarged broken elevation of one side of the automatic reversing mechanism for elevating and lowering the upper beating elements;

Fig. '13 is a broken plan view, partly in section, of Fig. 12; and

Fig. 14: is an elevation of the opposite side of said mechanism.

Referring to the drawings the numeral 1 is used to designate the corner angles or members of a suitable frame having front and rear horizontal bars 2 and also pairs of front and rear vertically disposed channels 3. Extending from front to rear of the frame and having their ends rigidly secured to the vertically disposed channels 3 are two pairs of parallel angles l and between each pair of angles 4: I have pivotally mounted a plurality of rockers 6 having arms 7 connected thereto and offset to wards the center of the main frame, as disclosed in Fig. 1 of the drawings. The rock crs 6 and arms 7 connected thereto are arranged in opposite pairs each pair of said arms being connected to a transversely arranged rod 8 which forms the beating element. When these arms 7 are moved to the uppermost position where the rods 8 engage the lower side of a mattress 9, hereinafter more fully described, the said rods 8 or beating elements are equally spaced.

The rockers 6 are connected by means of suitablelinks 11 to crank levers 12 also pivotally mounted between the angles 4 and are connected pivotally to stems of cam straps 14L rotatably mounted upon cams 16 on a lower power shaft 1? whereby rotation of said shaft 17 will cause said cams 16 to rock the rockers 6, through the medium of the links 11; and thereby impart a reciprocating movement to the arms 7 and rods or beating elements 8 on the free ends I of said arms 7. I

The ends of the rods 8 are curved to prevent damage to the ticking of the mattress 9 or to the resilient mattress support hereinafter more fully described.

Also extending from the front to the rear of the main frame I have provided a second pair of angles 18 resting upon and rigidly secured to the horizontal members 2 hereinbefore described, to which angles 18 I have connected what I term transverse lofting bars 19, said bars 19 being arranged alternately with the bars or beating elements 8 when said bars 8 are in their upper most positions, the front and rear bars 19 being preferably straight and the succeeding bars 19 each being a little more arcuate or curved toward the center of the machine, the innermost bars being more greatly curved or arcuate than the intermediate bars so that the greatest distance between said bars and the mattress 9 directly over them will be greatest at the approximate center of said mattress 9, as disclosed in Figs. 1 and 3 of the drawings, the purpose of which will hereinafter be more fully set forth.

Rollers 21 are mounted upon the outer sides of the angles 18 in order to provide suitable bearings for slidably supporting the lower frame 22 of a circular mattress sup port 23, said mattress support 23 being rotatably mounted upon the frame 22 by means of suitable rollers mounted upon the said frame 22 and rotatably engaging and supporting the inwardly turned flanges of the mattress support 23 one of which rollers is disclosed in Fig. 10 of the drawings.

The resilient circular mattress support 23 is provided with interlaced webs 26 which are in turn secured at their opposite ends to the circular mattress support 23 by means of suitable springs 27, as disclosed in Figs. 3, 4 and 5 ofthe drawings. By means of this rotatable circular resilient mattress support mattress 9 may be supported above the lower "beating elements or rods 8 and as said rods are reciprocated and strike against the lower surfaces of the webs 26 the blow will be imparted to the bottom of the mat tress 9 upon said webbing 26, and as said webbingis flexible and resilient it will be the same, in effect as if the bars 8 struck the lower surface of the mattress 9 itself.

The mattress support 23 is moved inwardly until the rear end thereof strikes a stop pin 28 which will position the mattress 9 directly in correct operative position relatively to the beating elements.

The power shaft 17 is rotatably mounted within suitable bearings 31 and is provided at one end with a female clutch member 32 arranged to be engaged and rotated by means of a male clutch member 33 on a shaft 36 also mounted within a suitable bearing 37 and having flywheel driving pulley 38 on the end thereof, as disclosed in Fig. 2 of the drawings.

The male clutch member 33 is operated to engage and disengage the female clutch member 32 by means of the usual lever 4L1 which extends forwardly and projects beyond the horizontal frame member 2 at the extreme right hand end of the front of the machine.

The right hand channel of the lower portion of the supporting frame 22 is provided with a spline or rod 4-2 having a projection l3 on the rear or inner end thereof. A bell crank latch n is pivotally mounted upon the horizontal frame member 2 and isarranged with a vertical portion 46fa'rranged tobe moved in front of'the front end of the rod 42 by the {clutch lever 4l when the same is actuated to connectthe clutch memnect the clutch members" 321 and Yan'd thereby prevent further operation of the lower beating elements or rods 8the Vertical 2 portion 46' ofthe' latch44 is] moved away from in front'of the frontend of'the rod 42 thereby unlockingor releasing thesli d able frame 22 of the mattress support 23 to permit withdrawal thereof; by means of a 3 suitable spring '48, said' movement' of said latch being permittedby a'notch 47 in the latch 44 which notch 47, engagesthe oifo r outerside of the lever 41. i

As the sliding frame 22 is withdrawn from operative relation to the beater elements 8 the side of the rod 42 engages the vert cal portion 46 of the latch 44 and thereby preventsamovement of said l'atchr44 which will permitthe'lever'41 to, be actuated to again connect the clutch members 32 and 33 and thereby preventing operation of the beaters whilesaidsupport is withdrawn fromoper'a 7 d p I V f upper end w th a bevel gear 83 which meshes tive r'elationto, said beating elements.

From the foregoing it isievident that the fmattress support 23 cannot be withdrawn while the clutch 32, 33 is engaged to operate the beating elements 8 and also that said beating elements cannot be operated while v the support is withdrawn.

Arranged upon each corner of the main frame or on the corner angles 1 thereof I have. provided vertically disposed rotatable threaded rods 51 whichrods 51 Iar'een'gaged by the corners ofa vertically movable frame 52 provided with two pairs of parallel angles 53 similar to the angles 4 which support the lower rockers 6 and arms 7 with heat;

ing elementsor rods.8.

Mounted between the angles 53 are similar rockers 54 also having inwardlyoffset'aims 56, each pair of arms connected to and operatinga second set of beatingelements or rods 57, thereby providin and lower beating elements.

The rods 57 of the upper beating elements;

are arranged alternately with the -r'ods8 of th lower heating element so thatwhen both ing opposite sides of the mattress 9 said in tress will assume a corrugated shape as disclosed in Fig. 3 of the drawin s and the .4 P3 7 1 upper heating elements 5'? will be directly over and opposite the lofting rodsd19 which the opposite side i are. arranged below or on of the mattress.

g a pair of upper er and lower beating elements are en-f The rockers 54 are connected by" means ofliiilis 591th cranks also pivotally mounted between the "angles 53 and actuated by suitable cam straps 62 mounted upon cams 63 secured to and rotated by an upper shaft 64 mounted within suitable bearings 66 on the Vertically movable frame 52. The shaft 64' is alsoprovided with amale clutch member 67. whichengages a female clutch member 68 mounted upon an aligned'shaft 69 mounted "within a suitable bearing 71; said the approximate center thereof, as disclosed in Figs. 2 and 3 6f the "drawings. The lower end of the shaft 7 4 is provided with a bevel ge r 7 mentioned.

The clutch member 67 is operated to engage and disengage the clutch. member 68, by means of' 'an operating lever 7 8 whose outer end rests within a suitable support79 and whose inner end is connected by means of a link 81 with alever 82 connected with said 7 male clutch member 67 whereby the upper beating elements may be operated i11 dependently oft the "lower heating elements.

The vertical shaft is also provided at its with two bevel gears '84 and 86 which are loosely mounted upon a horizontally disposed shaft 85,]thereby rotating said gears 84 and 86 in opposite directions, said gears 84and 86 being provided with clutch portions 87 and 88 arranged to engage with clutch collars89 and 91 respectively which are slidably 'keyed to horizontally disposed shaft'85, as disclosed in Figs. 3 12 and 13 v of the drawings,

A shifting rod 92 is,slidably mounted to themaiii frame ofthefinachine and is provi'ddwith connections "93. to the clutch collars 89, and 91, said shift rod 92 being also provided with stops 934 and 94 which are arranged to be engaged by lexrs 95 and pivotally mounted on said frame and connected with a bell crank lOl yas disclosed in Figs. 1 and 3 of the drawings, and to the .bell cranlrilOl have connected a vertically] disposed rod 102 having stops 103and1104 thereon which are arranged to be engaged by an actuating arm 105 mounted upon the vertically movable upper beat-' ing frame 5221s disclosed in Figs. 2 and 3 of the drawings, for the purpose of stopping gear 76 which meshes with a similar "on the power shaft 36 hereinbefore further movement of the said vertically movable frame 52, in a manner and for a purpose hereinafter more fully set forth.

The vertical rod 102 is'connected at its lower end with a pivotally mounted lever 106 provided with a projecting handle 10?.

fit each end of the horizontal shaft there bevel gears 109 which mesh with. bevel gears 111 at the upper ends of the adjacent vertically disposed threaded rotatably mounted within the corner angles 1 of the main frame, and also with bevel gears 112 on front and rear horizontally disposed shafts llet'which are suitably and rotatably mounted within suitable bearings, said shafts extending to the opposite corners of tne machine.

The bevel 111 and 112- are of same diameter but. of a smaller diameter than the gears 1 the . l)'j gears may be rotated at the same speed and from the same gear 109 on the shaft 85.

The opposite ends of the shaft 11% are each provided with suitable bevel gears 110 which mesh with similar gears 117 on the upper ends of the adjacent vertically disposed threaded rods 51 whichelevate and lower the upper beating frame In order to strip the mattress 9 from the upper heating elements when a thin mat tress of inexpensive ticking is being beaten I have provided strippers which are in the form of parallel rods 121 arranged between and alternately with the upper bea rods or elements 57 so that when the said mattress is being beaten the strippers will pre vent the rebound of the mattress irom coiling or twining around the said upper beating elements 57.

These stripping rods 121 are depended from the frame and er; end a sullicient distance beyond the ends or the ing elements 57 to clear the same. 7

In operation the support 22,.with its resilient rotatable portion 23 is slidably moved outwardly toward the front of the machine as disclosed in dotted lines in Fig. 1 of the drawings and the mattress 9 is placed thereon and approximately within the center of said support 23 as disclosed in full lines in 5 of the drawings the out ward movement of the supports 22 and 23 being limited by the extended portion of the rod 1-2 mounted upon the side of whereby both of said.

pper beat the frame or support 22 as hereinbefore described.

l l hile the support 22 is in an outward or inoperative positi n the rod 42 on the side thereof will prevent the latch le and the notch 4L7 therein from releasing the clutch operating lever 41 so that the lower beating elements cannot be operated while the said support is extended.

When. however, the support 22 is moved inwardly to an operative position and against the stop 28, the latch 14 may be moved to release the lever 41 so that the lower heating elements may be operated.

By moving the lever 106 through the medium of its projection 107 the shifting rods 102 and 92 are actuated to move the clutch collar 89 into engagement with the clutch portion 87 of the gear 8& and thereby rotate the shaft 85, and the various and several connecting shafts and gears to rotate the vertically disposed threaded rods in a direction which will lower the upper beating element frame 52 until it has attained the desired elevation with respect to the inattress 9 upon the resilient rotatable support 23.

Should the operator inadvertently neglect to release the lowering mechanism when the frame has reached the required level, the bracket 105 on the frame 52 will engage the lower stop 104: on the vertically disposed shift rod 102 and thereby move the same downwardly to disengage the clutch collar 89 from the clutch member 87 of the gear 84: and thereby automatically stop the said frame 52.

l t hen the shift roo 102 is moved upward to shift the clutch collar 91 into engagement with the clutch portion 88 of the gear 85 the bracket 105 will likewise engage the upper stop 103 on said rod 102 before the limit of movement of said frame 52 is reached and thereby actuate said rod 102 to disengage the said clutch collar 91 from the clutch portion 88 of the gear 86.

hen either collar 89 or 91 is thus disengaged, the tension of the springs 99 will operate to hold the levers 95 and 96 against the steps 97 and 98 respectively, on the main frame andthereby engage the stops or pins 93 and 9% of the shifting rod 92 and hold them in neutral or disengaged position, to prevent further rotation of the shaft 85 and tnereby prevent further movement of the frame 52.

When the upper beating elements have been moved to the correct position relatively to the mattress 9 the clutch levers ll and 78 are moved to cause their respective clutch members to engage and rotate the shafts 17 and 6t and thereby actuate the upper and lower beating elements 57 and 8 respectively to reciprocate and deliver a succession of rapid blows to the mattress 9 and on opposite sides thereof and at alternate points on said opposite sides, thereby rapidly corrugating the mattress as disclosed in Fig. 3 of the drawings. which operation will uniformly distribute the stutfing within the mattress. As these blows or strokes are not vertical or lateral to the mattress 9 but move arcuately it is evident that said blows will tend to move the stuffing within the mattress and as the rotatable resilient support is rotated the position of the mattress 9 thereon is changed relatively to the direction and position of said strokesuntil a uniform distribution of stuffing within the mattress has been effected. i

After a uniform distribution has been thus effected, the lever etl'is moved to disengage the clutch member 33 from the'clutch member 32 which rotates the lower'sh'aft '17, thereby preventing further operation of the lower beating elements 8. I

vThis cessation is caused at a point where the lower heating elements 8v are at their v mg ajpa lr of beating elements; and means lowest position'so that said beating elements Swill not interfere with. the arcuate lofting rods or support 19 when the frame 22 is finally withdrawn. V I As the upper beating elements 571C011- tinue to'operate the. mattress 9 is pressed downward by said elements 57 until the mattress comes into. contact with said lofting rods 19 which are positioned;directly opposite and on the underside of said mattress9.

As the said lofti ng rods 19 are arcuate and so positioned that the greatest distance between said'rods and the flexible bottom of the supporting frame23 is at the approximate center of said frame 23 andthe mattress 9 thereon, it is obvious that when the pressure of the upper beating elements is withdrawn, the resulting rebound imparted to the mattress 9 by the flexible webs 26 and springs 27 attached thereto will be greater at the center of said mattress 9 than at other portions thereof, with the resu'l t'thatthe stuffing within the mattress 9 will be lofted toward the center of saidmattress.

This is a desired condition in mattresses as more stuffing is required at the center than at other portions thereof.

The, clutch lever 78 is then actuated, to disengage the upper beating 'elementsfrom the power, the lever 106 is actuated'to raise the frame 52 upwardly away from themattress and the support 22 is moved to withdraw the mattre-ss 9 from between the beating elements. k

A mattress beating machinecomprising a resilient support arranged to support a mattress to expose both sides thereof simultaneously tothe action of heating elements; beating elements arranged on both sides of said support and mattress thereon, said elements comprising parallel bars arranged alternately on opposite elements whereby a mattress may be corrugated successively during the heating process to uniformly distribute stuffing within the mattress; means for operating either heating element independently of the other; and lofting means comprising parallel supporting bars arranged alternately with the bars of one element and opposite the bars of the opposite element, each successive inner bar being arranged farther from the mattress at the center than the adjacent outer bar whereby the support thus afforded will be farther from said mattress at the center than at the edges of said mat- "tress whereby said mattress may be lofted to loft stuffing toward the center of the mattress when the bars of the opposite beating element only are being operated.

28. A mattress beating machine comprising upper and lower beating elements com prisingparallel bars, the bars of the upper element being positioned alternately with respect to the bars of the lower beating element; means for operating either beating element independently of the other element; a resilient mattress support arranged between the beating elements and adapted to simultaneously expose both sides of a mattress thereon to the action of said beating elements; a stripping means arranged between the bars of the upper element and arranged to strip the mattress therefrom; and a lofting means comprising arouate parallel bars arranged below the support and between the bars of the lower heating element said bars increasing in distance from the mattress toward the center thereof whereby a greater rebound may be imparted by the resilient support to the mattress thereon 10 when beaten by the upper beating element only to loft the stufling within said mattress.

In Witness whereof I hereunto set my signature.
